Abstract A Gram-stain negative, non-flagellated, beige-pigmented, circular, catalase-positive, oxidase-positive bacterium, designated G4T, was isolated from gut microflora of top shell (Trochus maculatus Linnaeus) collected from Diwanggong market, Weihai, PR China. The novel isolate was able to grow at 4–42°C (optimum 25–33°C), pH 7.0–9.0 (optimum 6.5–7.0) and with 0.0–11.0% NaCl (optimum 2.0–3.0%, w/v). Analysis of 16S rRNA gene sequence revealed that strain G4T shared the highest 16S rRNA gene sequence similarities with Oceaniglobus YLY08T (96.6%), followed by Oceaniglobus indicus 1-19bT (95.3%). The genome of strain G4T, with 32 assembled contigs, was 4.5 Mb long with a G + C content of 65.3 mol%. DNA–DNA hybridization values of the isolate against the closely related type strains were far below the 70% limit for species delineation. The average amino acid identity, average nucleotide identity and digital DNA-DNA genome hybridization relatedness between strain G4T and the closely related members of the genus Oceaniglobus, Oceaniglobus indicus1-19bT and Oceaniglobus ichthyenteri YLY08T were 71.3, 76.4 and 20.0%, and 75.0, 76.3 and 19.4%. The major cellular fatty acid was summed feature 8 (C18:1ω7c and/or C18:1ω6c). The sole respiratory quinone detected was Q-10. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol and phosphatidyldimethylethanolamine. The results of phenotypical, phylogenetic and biochemical analyses indicated that strain G4T represents a novel species in genus Oceaniglobus within the family Rhodobacteraceae, for which the name Oceaniglobus trochenteri sp. nov. is proposed. The type strain is G4T (= MCCC 1K04356T = KCTC 82506T).

A Gram-negative, non-spore-forming, non-motile, rod-shaped, red-pigmented strain, designated YIM 007T, was found as a contaminant on an agar plate in the laboratory of Yunnan Institute of Microbiology, China. The optimum growth pH and temperature for the isolate were 7.0–7.5 and 30 °C, respectively. The predominant respiratory quinone was MK-8. The polar lipid profile consisted mainly of various unknown phosphoglycolipids and glycolipids. The major cellular fatty acids were C16 : 1 ω7c, C16 : 0, C17 : 0 and C17 : 1 ω8c. l-Ornithine was detected in its peptidoglycan. The DNA G+C content was 64.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain YIM 007T showed 16S rRNA gene sequence similarity levels of 86.8–92.1 % to the other described Deinococcus species. Based on the high 16S rRNA gene sequence divergence and phenotypic differences, it is proposed that the unknown strain should be classified as a novel species in the genus Deinococcus with the name Deinococcus yunweiensis sp. nov. The type strain is YIM 007T (=KCTC 3962T=DSM 17005T).

AbstractStrain M2T was isolated from the beach of Cuxhaven, Wadden Sea, Germany, in course of a program to attain new producers of bioactive natural products. Strain M2T produces litoralimycin and sulfomycin-type thiopeptides. Bioinformatic analysis revealed a potential biosynthetic gene cluster encoding for the M2T thiopeptides. The strain is Gram-stain-positive, rod shaped, non-motile, spore forming, showing a yellow colony color and forms extensively branched substrate mycelium and aerial hyphae. Inferred from the 16S rRNA gene phylogeny strain M2T affiliates with the genus Streptomonospora. It shows 96.6% 16S rRNA gene sequence similarity to the type species Streptomonospora salina DSM 44593 T and forms a distinct branch with Streptomonospora sediminis DSM 45723 T with 97.0% 16S rRNA gene sequence similarity. Genome-based phylogenetic analysis revealed that M2T is closely related to Streptomonospora alba YIM 90003 T with a digital DNA-DNA hybridisation (dDDH) value of 26.6%. The predominant menaquinones of M2T are MK-10(H6), MK-10(H8), and MK-11(H6) (> 10%). Major cellular fatty acids are iso-C16:0, anteiso C17:0 and C18:0 10-methyl. The polar lipid profile consisted of diphosphatidylglycerol phosphatidyl glycerol, phosphatidylinositol, phosphatidylcholine, phosphatidylethanolamine, three glycolipids, two unknown phospholipids, and two unknown lipids. The genome size of type strain M2T is 5,878,427 bp with 72.1 mol % G + C content. Based on the results obtained from phylogenetic and chemotaxonomic studies, strain M2T (= DSM 106425 T = NCCB 100650 T) is considered to represent a novel species within the genus Streptomonospora for which the name Streptomonospora litoralis sp. nov. is proposed.

Abstract Gram-positive, rod-shaped, spore-forming, thermophilic, acidophilic bacterium, designated strain skT53T, was isolated from farm soil in Tokyo, Japan. The strain grew aerobically at 37–55°C (optimum 50°C) and pH 4.0–6.0 (optimum 5.0). Phylogenetic analysis of the 16S rRNA gene sequence showed that the isolate was most closely related to the type strain of Effusibacillus consociatus (94.3% similarity). The G + C content of the genomic DNA was 48.22 mol%. MK-7 was the predominant respiratory quinone. The major fatty acids were anteiso-C15:0, iso-C15:0, iso-C16:0 and C18:3ω6c. The results of phenotypic and chemotaxonomic, 16S rRNA gene sequence similarity, and whole genome analyses support strain skT53T as representing a novel species of Effusibacillus dendaii sp. nov. is proposed. The type strain is strain skT53T (= NBRC 114101T = TBRC 11241T).

The taxonomic position of four Gram-negative, rod-shaped, golden-yellow-coloured bacteria isolated from marine sediments was determined. Analysis of the almost complete 16S rRNA gene sequences indicated that these isolates belong to the family Flavobacteriaceae. An unclassified bacterium, NBRC 15975, was found to be the closest relative, showing 16S rRNA gene sequence similarity of 93 %; other related genera shared only 87·9–90·5 % similarity. In contrast, the four isolates shared high levels of 16S rRNA gene sequence similarity (99·3–99·7 %) and high DNA–DNA reassociation values (93–104 %). The isolates could be differentiated phenotypically from other genera by the abilities to reduce nitrate and to degrade gelatin, casein and starch. The only respiratory quinone was MK-6, and the major fatty acids were iso-C15 : 0, iso-C15 : 1, anteiso-C15 : 0, iso-C17 : 1 ω9c and iso-C17 : 0 3-OH. The DNA G+C content was 38–40 mol%. Differentiating phenotypic characteristics and large phylogenetic distances between the isolates and previously published genera indicated that the isolates constitute a novel genus, for which the name Sediminicola gen. nov. is proposed. The type species is Sediminicola luteus sp. nov. (type strain CNI-3T=NBRC 100966T=LMG 23246T).

Gene Sequence Analysis

A Gram-negative, rod-shaped organism (CCUG 49520T) was isolated from the midgut of the mosquito Anopheles arabiensis. 16S rRNA gene sequence analysis demonstrated that this isolate is unique, showing <93 % similarity to species of the families Enterobacteriaceae and Vibrionaceae. The quinone system consisted exclusively of ubiquinone Q-8; the polar lipid profile consisted of the major compounds phosphatidylethanolamine and phosphatidylglycerol, a moderate to minor amount of two unknown aminophospholipids, an unknown phospholipid and two unknown polar lipids; the polyamine pattern was characterized by the predominant compound 1,3-diaminopropane and showed some significant differences when compared with members of the Enterobacteriaceae and Vibrionaceae. On the basis of 16S rRNA gene sequence analysis in combination with chemotaxonomic data, strain CCUG 49520T is considered to represent a new genus and species, for which the name Thorsellia anophelis gen. nov., sp. nov. is proposed. The type strain is CCUG 49520T (=CIP 108754T).

Respiratory Quinone

A Gram-stain-positive, halotolerant, neutrophilic, rod-shaped bacterium, strain MF38T, was isolated from a saline–alkaline soil in China and subjected to a polyphasic taxonomic characterization. The isolate grew in the presence of 0–15 % (w/v) NaCl and at pH 6.5–8.5; optimum growth was observed with 3.0 % (w/v) NaCl and at pH 7.0. Chemotaxonomic analysis showed menaquinone MK-7 as the predominant respiratory quinone and anteiso-C15 : 0, anteiso-C17 : 0, iso-C15 : 0, C17 : 0 and C16 : 0 as major fatty acids. The genomic DNA G+C content was 35.3 mol%. 16S rRNA gene sequence similarities of strain MF38T with type strains of described Gracilibacillus species ranged from 95.3 to 97.7 %. Strain MF38T exhibited the closest phylogenetic affinity to the type strain of Gracilibacillus dipsosauri, with 97.7 % 16S rRNA gene sequence similarity. The DNA–DNA reassociation between strain MF38T and G. dipsosauri DSM 11125T was 45 %. On the basis of phenotypic and genotypic data, strain MF38T represents a novel species of the genus Gracilibacillus, for which the name Gracilibacillus ureilyticus sp. nov. (type strain MF38T =CGMCC 1.7727T =JCM 15711T) is proposed.

Two bacterial strains, PC-142 and PC-147T, isolated from poultry litter compost, were characterized with respect to their phenetic and phylogenetic characteristics. The isolates were endospore-forming rods that were reddish in colour after Gram staining. They were catalase- and oxidase-positive, were able to degrade starch and gelatin and grew at 15–40 °C and pH 5.5–10.0. The predominant fatty acids were anteiso-C15 : 0, iso-C15 : 0 and iso-C16 : 0, the major respiratory quinone was menaquinone MK-7, the cell-wall peptidoglycan was of the A1γ type and the G+C content of the DNA was 58 mol%. The 16S rRNA gene sequence analysis and phenetic characterization indicated that these organisms belong to the genus Paenibacillus, with Paenibacillus pasadenensis SAFN-007T as the closest phylogenetic neighbour (97.5 %). Strains PC-142, PC-147T and P. pasadenensis SAFN-007T represent a novel lineage within the genus Paenibacillus, characterized by a high DNA G+C content (58–63 mol%). The low levels of 16S rRNA gene sequence similarity with respect to other taxa with validly published names and the identification of distinctive phenetic features in the two isolates indicate that strains PC-142 and PC-147T represent a novel species of the genus Paenibacillus, for which the name Paenibacillus humicus sp. nov. is proposed. The type strain is PC-147T (=DSM 18784T =NBRC 102415T =LMG 23886T).

The isolate was catalase-, oxidase- and arginine dihydrolase-positive, and able to grow between 15 and 45 °C and between pH 5.5 and 9.0. The predominant fatty acids were C16 : 1/iso-C15 : 0 2-OH and C16 : 0, the major respiratory quinone was ubiquinone 8 and the G+C content of the genomic DNA was 63 mol%. 16S rRNA gene sequence analysis indicated that strain E4FC31T belonged to the class Betaproteobacteria and was a member of the family Neisseriaceae. Its closest phylogenetic neighbours were Aquitalea magnusonii and Chromobacterium violaceum (<94 % 16S rRNA gene sequence similarity). Phylogenetic analysis and phenotypic characteristics of strain E4FC31T suggest that it represents a novel species of a new genus, for which the name Gulbenkiania mobilis gen. nov., sp. nov. is proposed. The type strain of Gulbenkiania mobilis is E4FC31T (=DSM 18507T=LMG 23770T).

A novel Gram-negative, aerobic, coccoid-shaped strain designated S 113T was isolated from a polluted-soil sample collected in Jiangsu Province, China. A polyphasic taxonomic study including phylogenetic analysis based on the 16S rRNA gene sequence and determination of phenotypic characteristics was performed on the new isolate. The highest 16S rRNA gene sequence similarity was 96.8 %, with Hansschlegelia plantiphila S1 T. The predominant respiratory quinone was ubiquinone 10 (Q-10). The major fatty acids were C18 : 1ω7c and C16 : 0. The G+C content of the DNA was about 65.7 mol%. DNA–DNA hybridization experiments showed 44.9 % relatedness for strain S 113T with its closest relative, H. plantiphila NCIMB 14035T. The dominant phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmonomethylethanolamine and phosphatidylcholine. The results of our polyphasic taxonomic analysis indicate that strain S 113T represents a novel species within the genus Hansschlegelia, for which the name Hansschlegelia zhihuaiae sp. nov. is proposed. The type strain is S 113T ( = DSM 18984T  = CCTCC AB 206143T  = KCTC 12880T).

Two bacterial strains, MC-246T and MC-247, were isolated from municipal urban waste compost and characterized by a polyphasic approach. Both isolates were Gram-stain-variable, endospore-forming rods that were catalase-, oxidase- and β-galactosidase-positive, and able to grow at 25–50 °C and pH 7.0–9.0, with optimum growth at 37 °C and pH 7. The predominant cellular fatty acids were anteiso-C15 : 0, iso-C15 : 0, iso-C16 : 0, anteiso-C17 : 0 and iso-C17 : 0; the major respiratory quinone was menaquinone MK-7; the cell wall peptidoglycan was of type A1γ; and the DNA G+C content was 49 mol%. These characteristics, as well as data from 16S RNA gene sequence analysis, showed that these strains were affiliated with the genus Paenibacillus; the type strains of Paenibacillus ginsengarvi and Paenibacillus hodogayensis were among their closest neighbours (<94.2 % sequence similarity). Nevertheless, the hypothesis that strains MC-246T and MC-247 could represent a novel species was supported by the low 16S rRNA gene sequence similarity values shared with other members of the genus Paenibacillus and by the observation of distinct biochemical and physiological traits. Strains MC-246T and MC-247 shared 99.6 % 16S rRNA gene sequence similarity and showed almost identical MALDI-TOF mass spectra, but could be distinguished at the phenotypic and genotypic level. However, DNA–DNA hybridization between strains MC-246T and MC-247 resulted in values above 70 % indicating that both organisms represent a single species, for which the name Paenibacillus residui sp. nov. is proposed; the type strain is MC-246T (=DSM 22072T =CCUG 57263T).
